Revsion history of io-classes

1.6.0.0

Breaking changes

• strict-stm, strict-mvar and si-timers are now public sublibraries of io-classes package.
• Moved io-classes-mtl to io-classes as a public sublibrary.

1.5.0.0

Breaking changes

• MonadST depends on PrimMonad.
• Provide a default implementation of withLiftST.
• Added annotateIO to MonadThrow (only supported for ghc-9.10 or newer).

Non-breaking change

• Add writeTMVar to MonadSTM.

• strict-stm, strict-mvar and si-timers were moved to io-classes as public sublibraries. You can import then in *.cabal files with the following syntax io-classes:strict-stm or io-classes:{strict-stm, si-timers}. See the Multiple public libraries subsection of Internal Libraries section in the cabal documentation.

  Note: some time in the future we will deprecate Hackage packages strict-stm, strict-mvar and si-timers. If one will want to use the namespace for a non io-classes related packages please contact the maintainer.

1.4.1.0

Non-breaking changes

• New dependency on primitive package
• New stToIO in MonadST, which is simpler to use than the existing withLiftST, and depends on the primitive package's PrimState (#141).

1.4.0.0

Breaking changes

• Removed deprecated module Control.Monad.Class.MonadVar.

Non-breaking changes

• Fixed some module haddock typos.

1.3.1.0

Non-breaking changes

• Added forkFinally to MonadFork.

1.3.0.0

• io-sim-1.3.0.0.

• Support ghc-9.8.

1.2.0.0

Non-breaking changes

• Add new MonadInspectMVar class with an inspectMVar function for accessing an MVar in an underlying monad (if applicable). This is mainly useful for io-sim, since the underlying monad is ST. IO has no underlying monad, so the provided instance for IO defaults inspectMVar to tryReadMVar.
• Add some Haddock documentation to MonadDelay

1.1.0.0

Breaking changes

• Control.Monad.Class.MonadMVar is now deprecated in favour of Control.Concurrent.Class.MonadMVar.

Non breaking changes

• Fixed building haddocks with ghc-8.10.

1.0.0.1

Non breaking changes

• Support ghc-9.6.

1.0.0.0

Breaking changes

• MonadMonotonicTime morphed into MonadMonotonicTimeNSec which supports getMonotonicTimeNSec from "base". MonadMonotonicTime can be found in new package si-timers.
• A simplified MonadTimer which is using time in microseconds encoded as Int rather than DiffTime. The previous interface can be found in the package si-timers.
• The non standard timer API is moved from MonadTimer to a MonadTimerFancy type class which can be imported from Control.Monad.Class.MonadTimer.NonStandard module.

Non breaking changes

• Added registerDelayCancellable to Control.Monad.Class.MonadTimer module.

0.6.0.0

0.5.0.0

• fixed tryTakeMVarDefault, takeMVarDefault, putMVarDefault and isEmptyMVarDefault.
• Implemented the proper readMVar semantics.
• Added tryReadMVar to MonadMVar type class.
• Moved MVarDefault to io-sim package.

0.4.0.0

• support ghc-9.4 (except on Windows input-output-hk/io-sim#51)

0.3.0.0

• added missing MArray instance for WrappedSTM
• added monoid instances for WrappedSTM
• added threadStatus method of MonadFork class
• removed linktTo and linkToOnly
• added labelTChan
• added flushTQueue
• split MonadSTM into submodules in a similar way that the stm package is.
• added TChan, TSem and TArray
• added interruptible and allowInterrupt to MonadMaskingState type class.
• added unGetTQueue & unGetTBQueue
• support ghc-9.2 & ghc-9.4
• added MonadMVar

0.2.0.0

• First version published on Hackage.
• added lengthTBQueue to MonadSTM; io-classes now depends on stm-2.5.0.0.

0.1.0.0

• Initial version, not released on Hackage.
